Thanks for your advice. I will take it. I have done more research since I posted and have also concluded that hiring a Geotechnical Engineer would be in our best interest.
We do not have a post tension slab and we are having severe cracking in the front section of our home (tile flooring with wide gaps forming and hollow sounding, walls cracking, front porch sinking as well as sidewalk to front door, brick wall wobbly, sink holes around front yard to name a few)...
